With about half of Siler City's homes built before 1980, buried water pipe under concrete floors here is often decades old and more prone to pinholes and wear. A plumber confirms the leak, locates it and repairs it through the slab or replaces the run above the floor. Call the number on this page to be connected with a local plumber in Siler City.

Siler City background
Siler City is a manufacturing town in western Chatham County with a historic downtown along North Chatham Avenue. Census survey figures put the median home at 1980, with roughly half built earlier and a large share from the 1950s. Water now comes from TriRiver Water, the City of Sanford's regional utility, which took over the town system in 2025 and draws from local reservoirs. That supply is sensitive to drought, and dry spells have brought voluntary restrictions before, so a leak that runs for weeks wastes water the whole community depends on.
What to do now
- Shut off every water use. Faucets, toilets, the washer, the ice maker and any outdoor hoses.
- Watch the meter. Note the reading, wait an hour and look again. Any change is a leak.
- Close the main at the house. If the meter then stops, the leak is inside; if not, it is on the yard line.
- Isolate the hot side. Close the cold supply valve on the water heater. A meter that stops now points to a hot water line.
- Limit damage. If water is coming up through the floor, leave the main closed, move belongings and call.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Warm floor along a path from the water heater | Leak in a buried hot water line |
| Meter moves only when the main is open | Leak inside the house, possibly under the slab |
| Meter keeps moving with the main closed | Leak in the service line in the yard |
| Musty smell and damp baseboards | Slow leak wetting the floor and wall bottom |
| Toilet tank refilling on its own | Worn flapper, not a slab leak |
If more than one row fits your house, mention each to the plumber. A warm floor plus a meter that stops with the main closed is a strong case for an indoor slab leak, while a yard-line leak needs a different repair altogether.
Cost factors
- Time spent isolating and locating the leak
- Whether the pipe is copper from the 1950s through 1970s and likely to fail again nearby
- Spot repair through the concrete versus rerouting through walls or the attic
- Flooring and wall repairs after the work
- Permits through Chatham County Central Permitting & Inspections, which covers Siler City
